What type of cells in the retina are sensitive to light?

Rod and cone cells are the primary photoreceptors in the retina that are sensitive to light. Rod cells are responsible for vision in low-light conditions and provide black and white vision, while cone cells function in brighter light and are responsible for color vision and visual acuity. Together, these two types of cells allow the eye to detect and respond to light stimuli effectively.

Ganglion cells, amacrine cells, and bipolar cells play important roles in processing visual information, but they do not directly detect light. Ganglion cells transmit visual signals to the brain, amacrine cells help regulate the flow of signals between photoreceptors and ganglion cells, and bipolar cells connect rods and cones to ganglion cells. However, none of these cells possess the light-sensitive properties that define rods and cones.
